The lubrication of plant in the cement industry offers some quite unique challenges. Admittedly there are numerous items of plant that are commonly found in many other industries, gearboxes and bearings for example, of which there are many and diverse types. However, it is not so much the type of equipment that is the issue in this industry but the environment in which these items of plant are operating on a daily basis, which can also vary from season to season depending on the global location of these plants. It is this parameter alone which maintenance personnel operating in the cement industry must consider very carefully when both selecting and applying lubricants, because lubricants that work well in almost identical equipment in other, perhaps not so arduous conditions, might not be so effective in this industry. Let us consider some key applications which will hopefully throw some light on these nuances.
